To all whom it may concern:

Be it known that I, ERNST SGHUCI-IARD, engineer, a subject of the German llmp eror, residing at 1 Siid-lVest-Corso, Berlm-Fr1edenau, Germany, have invented new and useful Improvementsin digging-Machines, of which the following is a specification.

In the known methods of separating material in jigging machines, where the supply of the new material takes place at the surface of the material, which forms in the several settling compartments of the jigging machine comparatively high layers, it is necessary that the heavier grains, the separation of which forms the object of the process, should gradually work through their way on to the sieve or the deeper parts of the whole layer, where they come to rest and are finally discharged. It is clear that the resistance, which has to be overcome by the grains in order to reach the positions, from which they may be discharged, is very considerable. It is also obvious, that very considerable time is required for the heavy grains to pass through a comparatively hlgh layer of material. These circumstancesare the chief reason, why the jigging machmes at present in use have to be made of a yery considerable length, or why a comparatively large number of such compartments have to be placed in one row and used in succession in order to obtain a satisfactory separation. Moreover, the action of the jigging water upon the new material supplied from above upon the thick layer of material is considerably weakened owing to the fact that the water has to pass through the whole thickness or height of the layer placed upon the carrier before it reaches the new supply.

It is the object of thepresent invention to obviate these drawbacks of the known jigging machines. With this object in view the carrier is provided at the point of supply with an elevated portion, upon which the material to be separated is subjected in the form of a thin layer to the direct action of the jigging water. From this elevated portion, the products of the jigging operation pass over an adjacent inclined or step-shaped portion of the carrier directly to the points of discharge. The material is thus subjected at the supply end of the jigging machine to the full action of the jigging water, the separation of the material into heavier and lighter particles being effected very rapidly, almost instantaneously. The heavier particles of the material need not, therefore, work through a comparatively high layer of the material, but it is only required, that the particles should be transported or allowed to slide toward the discharge apparatus in the relative positions, which they have assumed at the entry into the jigging machine under the full action of the water. Owing to this arrangement, the

length of the various jigging compartments may be considerably shortened and the total number of the compartments may be reduced. This considerable shortening of the jigging compartments enables several compartments to be acted upon by a common jigging piston, whereby a great economy in the initial cost of the plant and in the working expenses may be obtained.

Several constructions of the invention are shown in the drawings by way of example.

Figures 1 and 2 are sectional elevations of two constructions and Figs. 3 and 4 are the corresponding cross sections. Figs. 5, 6, 7 and 9 are sectional elevations of several modifications, Fig. 8 shows a modification of the carrier.

The jigging machine shown in Fig. 1 conslsts of a single jigging compartment or sieve a. The supply of the material takes place from the funnel 6 upon the elevated portion of the settling carrier 0 which is subdivided into sections by vertically or slightly inclined non-perforated partitions d. The carrier may be composed of several parts or it may be made in one piece, the parts (Z being in the latter case non-perforated. The settling carrier is inclined downwardly from the point of supply. toward the discharge devices 6.

The jigging machine shown in Fig. 2 consists of a single jigging compartment or sieve The supply of the material takes place from the funnel 9 upon the elevated portion of the settling carrier h, which is subdivided into sections by vertically or slightly inclined non perforated partitions The carrier may be composed of several parts or it may be made in one piece, the parts 71 being in the latter case non-perforatcd. The settling carrier is inclined downwardly from the point of supply toward the discharge devices is.

In the construction shown in Fig. 1, the part extending from the elevated portion to the discharge device in step-shaped, while in the construction shown in Fig. 2 the said part is downwardly inclined but straight.

The jigging machine may of course be provided with any desired number of peri'orations or sieves.

In the constructions shown in Figs. 5 to 8 several troughs or grooves serving for the discharge of the divers separated materials and arranged directly side by side are used in. connection with a single operative portion oi the jigging sieve, a different product being obtained in caci groove or trough. The main advantage obtained by this arrangement is a further considerable reduction of the length of the machine. lvloreover, as the transport of the finished products to the discharge troughs or grooves takes place along the shortest possible path and Without any interruption, the etiiciency of the machine is greatly increased.

In the construction shown in Fig. 5 the operative portion of the jigging sieve or carrier adjacent to the point of supply is designated by the letter we, the several discharge grooves a are joined directly to this portion and are arranged side by side extending in the same direction.

ln the modification shown in Fig. 6, the operative portion Z of the carrier or sieve is corrugated and forms steps descending toward the discharge groove 0.

The carrier shown in Fig. 7 (litters from that shown in Fig. 6 in that the bottoms of the discharge grooves 27 are arranged along a descending line.

In the construction shown in Fig. 8, a portion. 25 o'tithe operative part of the carrier or sieve is formed fiat.

In the construction shown in Fig. 9 has the elevated portion of: the carrier or sieve downwardly inclined toward the portion, which serves for the discharge. lhe jigging machine shown in Fig. 9 consists of one jigging compartment 1. The material is supplied on to the elevated portion 2 of the sieve or carrier, which is inclined toward the portion 3 oi? the carrier, serving for the discharge of the various materials.
